Used as a key intermediate in the synthesis of pharmaceutical compounds, particularly in the development of kinase inhibitors for cancer treatment. Its aldehyde and boronic acid functional groups allow for dual reactivity, enabling sequential cross-coupling and condensation reactions in multi-step organic syntheses. Commonly employed in Suzuki-Miyaura coupling reactions to construct biaryl frameworks found in bioactive molecules. Also utilized in the preparation of sensors and functional materials due to its ability to form stable complexes with diols and amines.
